LUBRICATOR.

Original application filed May 17, 1915, Serial No. 28,803.

Serial No. 52,619.

To all whom it may concern ie it known that I, THOMAS K. ODEN, a citizen of the United States, residing at Sacramento, in the county of Sacramento and State of California, have invented a new and useful Lubricator, of which the following is a specification.

The device forming the subject matter of this application is a condensation displace ment double passage lubricator and the present application embodies matter divided out of my co-pending application, Serial No. 28,808, filed May 17. 1915 and purporting to set forth sundry improvements in an automatic flange oiler.

One object of the present invention is to improve the construction of the lubricator in so far as the means for heating the oil which the lubricator handles is concerned.

Another object of the invention is to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

The invention is shown in a single sectional view wherein is embodied a portion of a locomotive engine to which the device forming the subject matter of this application has been attached.

In the drawings there is shown a portion of a locomotive engine, comprising a boiler 1 and a cab 2. Attached to the boiler 1 is a bracket 41 supporting a reservoir 5 provided adjacent its upper end with a partition 6 defining a steam space 7. A pipe 8 1 opens through the partition 6 and extends downwardly to a point adjacent the bottom of the reservoir 5. A pipe 9 leads from the steam space of the boiler 1 t the top of the reservoir and communicates with the steam space 7 of the reservoir, a valve 10 being interposed in the pipe 9. At its lower end, the reservoir 5 is provided with a drain cook 11 and near its top and below the partition 6, the reservoir is equipped with a filling plug 12, whereby oil 14: may be introduced into the reservoir belovw the partition 6. The oil 14 ordinarily is forced out of the reservoir 5 by steam pressure applied through the pipe 9 but, at times, it may be desirable to operate the structure by compressed air. With this end in view, the reservoir 5 is provided with an air supply pipe 15 controlled by a valve 16. When air is delivered into the reservoir 5 through the pipe 15, oil will be forced outwardly through Specification of Letters Patent.

Divided and this application filed September 25,

the pipe (hereinafter mentioned) so long as there is any oil in the reservoir, above the upper end of the pipe 20.

Secured to the side of the boiler l or otherwise supported is a casing 17 provided with a glassfront 18. Mounted in the easing 17 are upright glass tubes 19 through which oil is supplied. by means of a pipe 20 controlled by a valve 20. The flow of oil through the tubes 19 is controlled by valves 21. A plurality ofpipes 22 are supported by the casing 17 and these pipes communicate with the tubes 19. The lubricator shown in this application is of general utility, but if the same is to be used in connection with a flange oiler, the pipes 22 may lead to the various drive wheels (not shown) of the engine.

The invention comprises a steam supply pipe 23 communicating with the steam space of the boiler 1, the pipe 23 being controlled by means of a valve 24. The pipe 23 is provided with a plurality of branches 25, each of which communicates with one of the pipes 22, below the casing 17, the branches 25 being controlled by means of valves 26. 4

In practical operation, steam pressure is supplied to the steam space of the reservoir 5, through the pipe 9, the valve 10 being opened. Pressure accumulating within the steam space 7 is transferred to the oil 14: in the reservoir 5 through the pipe 8, the oil 1% in the reservoir being forced to traverse the pipe 20, and thence passing into the several pipes 22 by means of the glass tubes 19. From the pipes 22, the oil is distributed to such elements as require lubrication.

Should the oil flow somewhat sluggishly, as is the case in cold weather, the oil may be warmed up by opening the valves 26 and 24, under which circumstances, steam will be delivered through the pipe 28 and its branches 25 to the pipes 22 below the casing 17.

. Iaving thus described the invention, what is claimed is 1. In a lubricator for flange oilers, the combination with a locomotive boiler, of a reservoir mounted on the boiler; a partition extended transversely of the reservoir and dividing the same into a steam space and an oil space; means for supplying oil to the oil space; a pipe opening through the partition and extended downwardly to a point adjacent the bottom of the oil space; a steam pipe leading from the boiler to the steam space; a valve in said pipe; a plurality of sight feed devices; a pipe leading from the oil space to the sight feed devices; a valve in said pipe and common to all of the sight feed devices; valves controlling each of the sight feed devices individually; independent outlets for the sight feed devices; a steam pipe leading from the boiler and having branches communicating respectively with the outlets; a valve in the last specified steam pipe and common to all of the branches; and valves in the branches and individual to the branches.

2. In a lubricator for flange oilers, areservoir; a partition extended transversely of the reservoir and dividing the same into a steam space and an 'oil space; means for supplying oil to the oil space; a pipe opening through the partition and extended downwardly to a point adjacent the bottom of the oil space; a source of steam supply communicating with the steam space; means for controlling said source; a plurality of sight feed devices; a pipe leading from the oil space to the sight feed devices; a valve THOMAS KNOX ODEN.
